Room Upgrades...

I am getting ready to leave for CSA in September. Currently, I am staying in a garden room. I really want to upgrade to a different location. Does anyone know how I do this? If I can do it when I arrive at CSA or if I take care of it before?

We had no problem upgrading onsite when we were at CTI in July. Took about 10 minutes tops...but, of course, the ocean view room (vs really bad, small garden view!) was available. We have found that working with the staff onsite at any Couples location is FAR easier...and nicer...then dealing with the Corporate office.
